A text editor.
To download installers for ted for Windows and Debian/Ubuntu, go to the releases.
On Debian/Ubuntu if you want automatic updates, you can also add my repository to apt, and just do
sudo apt install tedThere are a lot of text editors out there. ted doesn't do anything new. Here are some benefits of ted:
- Starts up immediately.
- Doesn't lag for reasonably-sized files.
- VERY small - a full ted installation is < 5 MB.
ted isn't incredibly complicated, but it does have some nice features you might not find in other editors.
- Customization of (pretty much) all colors and keyboard commands.
- Basic text editing like copy+paste, undo+redo, etc.
- Multiple tabs, each with a different file
- Split screen
- Auto-indent
- Syntax highlighting for C, C++, CSS, Go, HTML, Java, JavaScript, LaTeX, Markdown, Python, Rust, and TypeScript.
- Find and replace (with regular expressions!)
- Run build command, go to errors
- Run any shell command
- Autocomplete
- Go to definition
- Go to line number
- Indent/dedent selection, comment/uncomment selection
- Keyboard macros
After installing ted, you can just start using it like you would any other editor. The keyboard shortcuts are mostly what you'd expect them to be (Ctrl+o for open, Ctrl+n for new, Ctrl+s for save, etc.).
- Even if you don't want to change anything with ted, it's a good idea to look at the config file (see below) to check out all of the keyboard shortcuts!
- You can use Ctrl+f for "find", but if you want to search for something across multiple files, you can do
Ctrl+! (run shell command), then run
grep -n search_term *.py, for example (on Windows, you will need to have cygwin or something in your PATH for this to work). The-nensures that ted can jump to the results, just like jumping to build errors. - ted uses PCRE for regular expressions. This means that when using find+replace, if you want to
replace with a captured group, you need to use
$1, not (as you might expect)\1.
At any time, you can check out all the keyboard shortcuts, and add your own, by opening your ted.cfg file. To do this, press Ctrl+Shift+p to open the command palette, and select "open-config". There are several sections to this config file:
[core]for core settings[keyboard]for keyboard shortcuts[colors]for colors[extensions]for which file extensions should be mapped to which programming languages
Comments begin with #, and all other lines are of the form key = value.
Strings can span multiple lines and can either be delimited with " or `.
You can also include files with %include (note: the included file must start with a section header).
By default ted's settings will automatically update when you save the config file.
The core section's settings should be pretty familiar (font size, etc.) or should have comments on the previous line
explaining what they do. yes, on, and true are all synonyms, as are no, off, and false.
Keyboard shortcuts are of the form key combo = action, where action is an argument (number or string),
followed by a command. The commands match the things in the command palette (Ctrl+Shift+p), but : is added to the beginning to make
it clear it's a command.
A list of key names can be found here.
Colors are formatted like #rgb, #rgba, #rrggbb or #rrggbbaa, where r, g, b, and a are red, green,
blue, and alpha (transparency/opacity). You can use a color picker to help you out.
The extensions section is fairly self-explanatory.
You can set settings for specific programming languages like this:
[HTML.core]
# set tab width for HTML files to 2
tab-width = 2
Or settings for specific paths like this:
[/foo//core]
# set tab width in /foo to 17
tab-width = 17
# PCRE regex is supported! (the start is anchored but the end isn't)
[~/foo/.*\.hmtgf//core]
# set tab width for .hmtgf files in ~/foo
tab-width = 9
or put a file called .ted.cfg in any directory to have settings apply to files in that directory.
ted reads .editorconfig files automatically. you can override them by putting .ted.cfg
with the settings you want in the same directory.
To reset your ted configuration to the default settings, delete your ted.cfg file (~/.local/share/ted/ted.cfg on Linux,
C:\Users\<your user name>\AppData\Local\ted\ted.cfg on Windows) or move it somewhere else.
At the top of ted.cfg you will see a line which includes a theme.
To modify just one color in the theme, you can do something like
%include themes/classic.ted.cfg
[colors]
# replace background color with solid red!
bg = #f00
but you can also change to a different theme. Currently classic,
classic-light, and extradark are available.
No matter what you should include a built-in theme (even if you replace every single color), because more colors may be added to ted in the future, and you will want them to be set to something reasonable.
To record a macro, press Ctrl+F1/2/3/etc. While recording a macro, you won't be able to click or drag (this is to make sure your macro works consistently). Then press Ctrl+Fn again to stop recording. You can execute the macro with Shift+Fn.
Currently macros are always lost when ted is closed. The ability to save macros will probably be added eventually.
If you are working in a compiled language, like C, you can press F4 to compile your code. The default is to run make in
the current directory or one of its parents, depending on where Makefile is. On Windows, if make.bat exists, it will be run.
If a Cargo.toml file exists in this directory or one of its parents, F4 will run cargo build. You can set the default build command
in the [core] section of the config file.
You can press Ctrl+[ and Ctrl+] to navigate between build errors.
ted has support for two separate systems for IDE features. ctags
is very lightweight (a ctags installation is just 1.6 MB), and allows
for go-to-definition and limited autocompletion. This has very low CPU usage,
and will work just fine on very large projects (for large projects I would
recommend increasing tags-max-depth and turning regenerate-tags-if-not-found off).
LSP servers have lots of features but use lots of CPU and memory,
and may take longer to come up with completions/find definitions, especially
for large projects. However the LSP server runs in a separate thread, so it will not slow down
the ordinary text editing features of ted (unless the server starts
using 100% of all CPU cores, which is unlikely).
I would recommend trying out an LSP server if you're unsure about which one to use.
ted has support for LSP servers!
All the functionality listed below is only available if the server supports it.
You can Ctrl+Click on an identifier to go to its definition, or Ctrl+Shift+Click to go to its declaration, or Ctrl+Alt+Click to go to its type's definition.
You can also press Ctrl+D to get a searchable list of all functions/types where you can select one to go to its definition.
Press Ctrl+space to autocomplete. If there is only one possible completion, it will be selected automatically. Otherwise, you'll get a popup showing all possible completions. You can press tab to select a completion (or click on it), and press Ctrl+space/Ctrl+shift+space to cycle between suggestions.
When there is only one possible completion and the autocomplete window isn't open, a "phantom completion" will appear in gray text. Press tab to use it or continue typing if it isn't what you want. (This can be turned off in the settings if you don't like it.)
Hover over an identifier and press F1 to see its type and documentation ("hover information").
While your cursor is over an identifier, you can press F2 to highlight where it is used
("document highlights"). If you turn on highlight-auto in the settings, the highlights
will appear even if you don't press F2.
Press Ctrl+U to see usages of the identifier under the cursor. You can use Ctrl+[ and Ctrl+] to navigate between them, just like build errors.
If these features aren't working properly and you don't know why, try running ted in a terminal (non-Windows) or a debugger (Windows)
so you can see the stderr output from the server, or turn on the lsp-log setting and inspect ted's log (which is called log.txt
and is in the same directory as your local ted.cfg).
If an LSP server crashes or is having difficulty, you can run the lsp-reset command (via the command palette)
to reset all running LSP servers.
You can integrate any LSP server with ted by setting the lsp option in the [core.<language>] section of ted.cfg
to the command which starts the server. Some defaults will already be there, and are listed below. Make
sure you install the LSP server(s) you want and put the executables in your PATH (or change the lsp variable
to use the absolute path if not). You can also set configuration options with the lsp-configuration option.
Make sure the configuration you provide is valid JSON.
clangd is enabled by default. On Debian/Ubuntu you can install it with:
sudo apt install clangd-15 # replace 15 with the highest number you can get
sudo ln -s /usr/bin/clangd-15 /usr/bin/clangdOn Windows it can be downloaded from here.
For "go to definition" and "find usages" to work properly, you may need to create a compile_commands.json file.
The Go team's go-pls is enabled by default. You can download it
here.
Eclipse's jdtls is enabled by default.
You can download it here.
typescript-language-server is enabled by default.
You can download it by following
the instructions here.
texlab is enabled by default. You can download it
here.
python-lsp-server is enabled by default.
You can download it here.
rust-analyzer is enabled by default. You can install it with:
rustup component add rust-analyzerIf an LSP is too much for you, you can also use ctags
for autocompletion and jump to definition. You can run the :generate-tags command
at any time to generate or re-generate tags.
Ctrl+Click (go to definition), Ctrl+D (see all definitions), and autocomplete are all supported.
Autocomplete will just complete to stuff in the tags file, so it won't complete local
variable names for example.
Make sure you cloned ted with submodules (git clone --recursive ...).
If you didn't, run git submodule update --init --recursive.
To install ted from source on Linux, you will also need:
- A C compiler
- The SDL2 development libraries
- cmake
- imagemagick convert (for creating the .deb installer)
These can be installed on Ubuntu/Debian with:
sudo apt install clang libsdl2-dev cmake imagemagickThen run make -j8 release to build or sudo make install -j8 to build and install.
You can also run make -j8 ted.deb to build the .deb installer.
This installs ted for all users. If you just want to install it for yourself (or you don't have superuser access), you can do so with
mkdir -p ~/.local/bin ~/.local/share
GLOBAL_DATA_DIR='~/.local/share/ted-data' LOCAL_DATA_DIR='~/.local/share/ted' INSTALL_BIN_DIR='~/.local/bin' make install -j8On Windows, install Microsoft Visual Studio 2022, then find and add vcvarsall.bat to your PATH
(most likely lives at C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build).
Also, install the Visual Studio Installer Projects extension
(needed to build the .msi installer).
Next you will need the SDL2 VC development libraries: https://www.libsdl.org/download-2.0.php
Extract the zip, copy SDL2-2.x.y into the ted directory, and rename it to SDL2. Also copy SDL2\lib\x64\SDL2.dll
to the ted directory.
Then run make.bat release.
